Exhaustive methylation of 8,8a-diphenyl-l,2,3,5,6,8a-hexahydroimidazo[l,2-fl]pyrazine by NaH and CH3I in dehydrated tetrahydrofuran yielded 4,5-diphenyl-3,6-diazaocta-l,3.5,7-tetraene (i). Using 1 as an N,N donor ligand, cationic copper(i) complexes of the type [Cu(l)j]X-H2O (X- = C1O4-, n = 1.5; X- = PF6~, n = 0) and [Cu(l)(PPh3)2]X (X' = C1O44- or PF6-) have been synthesized. Compound 1 and its copper(i) complexes have been thoroughly characterised by 'H NMR (300 MHz). The Cum potential in [Cu(l)2]X-H2O is rather high, 0.92 V vs. SCE in CH2C12 at a glassy carbon electrode. This indicates that 1 is a potential n acid which preferentially stabilises copper(i) much more than copper(n). It is photoluminescent in fluid solution, its emission being somewhat quenched in [Cu(1)2]X-mH2O. The Royal Society of Chemistry 2000.
